TL;DR: DFirstCoder EV Check is an EV battery health check and monitoring feature that brings supported electric vehicle battery information into one place. Depending on the vehicle, it can display battery State of Health (SOH), individual cell voltage, charging information, battery-related diagnostic trouble codes (DTCs), and supported live battery and motor data. You can also view graphs, record and export supported live data, and generate a PDF report for review or sharing.

1. A Clearer View of Your EV Battery

An electric vehicle’s high-voltage battery is one of its most important systems, but understanding its condition can be challenging without relevant vehicle data. DFirstCoder EV Check brings supported EV battery information and related diagnostics together, helping drivers review the data their vehicle makes available in one place.

Depending on the vehicle, EV Check can display battery State of Health (SOH), individual cell voltage, battery-related diagnostic trouble codes (DTCs), supported live battery and motor data, and charging information. Graphs help visualize selected readings, while live-data recording, export, and PDF reports make the information easier to revisit or share

2. Understand Your EV Battery in Greater Detail

2.1 Battery Health Details

EV battery health is best understood by reviewing more than one reading. EV Check brings available State of Health (SOH), individual cell voltage, charging status, and other supported battery parameters into one view. These values help you understand the information reported by your vehicle and provide useful context when reviewing battery condition.

2.2 Live data motoring & Graphs

Battery and motor-related parameters can change as a vehicle operates. EV Check displays supported live data and presents selected readings in graphs, making it easier to follow changes during monitoring and review how values behave over time.

2.3  Smarter Used EV Deals

When considering a used electric vehicle, battery information can be an important part of your review. EV Check lets you examine supported battery data reported by the vehicle and generate a PDF report for reference. Use these results alongside the vehicle’s service and charging history, a test drive, and a professional inspection where appropriate. An EV battery report can support your decision, but it is not a complete assessment or guarantee of battery condition.

2.4 Battery-System Diagnostics

EV Check can display supported battery-related diagnostic trouble codes (DTCs), helping you identify issues recorded by the vehicle’s systems. Reviewing these codes alongside available battery data can provide a useful starting point for further diagnosis. If the DTCs are temporary, clear them in one-tap, instead of going to the workshop to clear by payment.

2.6 Battery Life Forecasting

EV Check estimates remaining driving range using available battery energy and average energy consumption. This battery life forecasting feature provides a practical estimate of how far you may be able to travel on the current charge and can help with trip planning.

3. Supported Vehicle

EV Check currently supports a limited range of vehicle models, and more are planned for future updates.

·North America: VW ID.4 and ID.buzz

·Europe: ID.3，ID.4，ID.5，ID.7，ID.Buzz

·Russia: ID3,ID4,ID6,ID7,ID.Unyx 06,ID.Unyx 07,ID.Unyx 08

Check the latest compatibility list for your region before using EV Check. A supported vehicle may not provide every parameter or feature.
